A library for rare dynamical event sampling in non-equilibrium systems, based on Transition Path Sampling (RTP-TPS) and Variational Path Sampling (VPS).

## Features

- **Rare Dynamical Event Sampling**: Efficiently sample rare events in active matter systems.
- **RTP-TPS**: Transition Path Sampling for Run-and-Tumble Particles.
- **VPS**: Variational Path Sampling for computing large deviation functions.
- **Analysis Tools**: Tools for estimating transition rates and large deviation rate functions.

## Installation

```bash
pip install activepaths
```

## Usage

### RTP-TPS Example (Conceptual)

```python
from activepaths.core import StateTuple
from activepaths.sampling.tps import is_reactive_indicator

# ... (Initialize trajectory and define reactant/product states) ...
# is_reactive = is_reactive_indicator(trajectory, is_reactant, is_product)
```

### VPS Example (Conceptual)

```python
from activepaths.sampling.vps import calculate_stochastic_action

# ... (Define system parameters and trajectory) ...
# action = calculate_stochastic_action(trajectory, mobility, force, dt, T)
```

## Development

To set up the development environment:

```bash
git clone https://github.com/USER/activepaths.git
cd activepaths
pip install -e .
pip install -r requirements.txt
pytest
```
